Invoke Rest API GET Method using Fiddler Tool

It isn't easy to write code every time to test our Rest API (Asp.Net Web API). Instead of writing the code to invoke API, we can invoke it by using Fiddler or PostMan tools. In this article, we discuss how to use the Fiddler tool to invoke our Asp.Net Web API.

Download the Fiddler tool at https://www.telerik.com/fiddler and install it. Open the Fiddler, and select Composer, as shown below.

Select the required method from the drop-down list and enter the API URL, as shown below. Here we are invoking Get() method. 

Here are mentioning content-type also as application/json. Now click on the Execute button, and it displays response status code on the left side, as shown below. Here it displays success status code 200.

Double click on the 200 status code line, it displays the response as shown below. Select the JSON tab to see the response.

In our next Asp.Net Web API examples, we will use Fiddler only to test our Asp.Net Web API.
